With most of the 222 occupied dwellings being separate houses and an average household size of 2.4 people, a reliable hot water system is essential for families, farming properties and retirees alike. Many homes still run older gas or electric units, so shifting to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical next step.
Cavendish enjoys strong sunshine, with average annual solar exposure of around 15.6 MJ/m² per day – roughly 4.3 kWh/m² of energy in the sun each day. That is ideal for a solar hot water heating system or a high quality heat pump hot water installation that draws warmth from the air. With a median total household income of $1,656 per week and many homes owned outright or with a mortgage, investing in long term hot water energy savings can make a real dent in running costs over the life of the system.
In 3314 Cavendish, most homes are larger detached houses, often with three or four bedrooms, so hot water demand is steady year round. That makes choosing the most efficient hot water system important, whether you are comparing heat pump vs solar hot water or weighing up solar hot water vs electric hot water. Brands like Rheem heat pump hot water, Sanden heat pump units and Rinnai solar hot water systems are popular options for an energy efficient hot water system, while Rheem solar hot water and Chromagen solar hot water are often chosen for properties with great roof space.
For many households, the hot water system price or cost is the first question. Typical bill savings in a Cavendish climate look like this:
• Replacing an old electric hot water system with a heat pump hot water system: around $350–$700 a year off bills. • Switching from gas hot water to a heat pump hot water system: around $250–$600 a year. • Moving from gas to a solar hot water system: around $200–$500 a year. • Upgrading an old electric to a modern electric hot water installation backed by solar PV: around $250–$500 a year.
Recent installs in Cavendish show this trend in action. There have been 33 efficient hot water installations recorded in the postcode, covering both heat pump and solar hot water installation projects. The big surge came around 2009, with 11 systems installed that year, followed by steady upgrades in 2011, 2012 and 2014. More recently, there has been a trickle of new systems each year from 2018 through to 2025, reflecting growing interest in electrification, lower running costs and all electric homes. Each new solar hot water tank replacement or heat pump upgrade helps cut local energy use and dependence on gas.
Hot Water Rebates, Tariffs & Savings
In Victoria, there is strong support for replacing ageing gas or electric hot water with efficient options. Cavendish homeowners can usually access Federal Small-scale Technology Certificates (STCs) for eligible systems, which effectively act like a solar hot water rebate or heat pump hot water rebate, reducing the upfront solar hot water price or cost or heat pump hot water price or cost. On top of that, state programmes can offer additional heat pump hot water rebate support or an electric hot water system rebate for certain efficient models. Combined, these hot water rebate VIC incentives can cut the system cost by a substantial percentage and shorten the payback period to just a few years, especially if you already have rooftop solar.
By running your hot water system during the day, using timers or solar diversion, you can push savings even further. Many Cavendish households are now comparing electric hot water vs gas hot water and finding that with rebates and solar, an efficient system can save hundreds of dollars a year while reducing emissions.
